Stalling on other Flex years
No other Flex model year has enough reports of stalling for a sheet of its own. See every Flex year.
What this problem usually is
Stalling reports are some of the most alarming on the site. The engine quits while the car is moving, sometimes on a highway and sometimes at a stop. Many owners say it restarted right away and the dealer found no stored code, which is part of why these complaints pile up before anything gets fixed.
What got replaced
Owners who name the part that was replaced mention the fuel pump (18 reports) and the battery (3 reports).
Recalls and investigations
2 recalls on the fuel and propulsion cover the 2014 model year. A recall on the same system isn't always the same failure, so read the defect text.
A component within the fuel pump electric module (PEM) may overheat causing a loss of electrical power to the fuel pump.
In the affected vehicles, the halfshaft retention circlip may not have been properly installed, and as a result, the halfshaft may move outward and disengage from the linkshaft while driving and without prior warning.

Should you keep driving it?
This page can't tell you that. 0 of 35 reports involved a crash and 1 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
